PATRICK MIHAN, or CHELSEA, MASSACHUSETTS. V

VENTILATOR Foe SHIPS.

sPEcrFIcATIoN forming part of Letters Patent No. 257,507, dated May 9, 1882 Application filed January 23, 1882.

To all whom rt may concern:

Be it known that I, PATRICK MIHAN, of Chelsea, in the county of Suffolk, of the State of Massachusetts, have invented a new and useful Improvement in Ventilators; and I do.

hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which Figure 1 is a side view; Fig. 2, a front elevation. Fig. 3 is a longitudinal and transverse section of a ventilator of my improved kind. Fig. 4t is a transverse section of its lower deflector and its water intercepting and discharging gutters.

The ventilator is intended principally for use on shipboard for ventilating the cabin or other part of a navigable vessel, although it may be employed to advantage on dwellings or various other Structures on land.

The nature of my invention is set forth in the claims hereinafter presented.

The said ventilator consists in part of a hood, A, having on one side of it a mouth, a, of a rectangular or other suitable form, and also having within and across it the said hood, and in rear of and arranged with the mouth, as represented, a partition, I). The ventilator, as represented, further consists of two deflectors, B 0, one of whichviz., the lower, 0, of 'them-is hinged at its upper part to the lower part of the partition I), the upper deflector, B, being hinged to the partition on or about on a level with the top of the mouth a. The lower deflector, when down or closed, inclines toward and rests upon the lower edge of the mouth, so the upper deflector, when up or closed,rests against the upper edge of the said month.

At its back the lower deflector is provided with a lip or flange, c, to extend from it upward in rear of and against the partition I), such lip,when the deflector is closed, serving to prevent any water on the deflector from passing underneath the partition and thence down into the-space below it. FlllilllEllllOIQ, the deflector O, at each side edge, has a lip or flange, d, projecting down from it over or into one of two inclined gutters, 6, arranged on the inner side of the hood, and leading to and through the lower corners of its month. There is also to the outer edge of the said deflector a lip or flange, f, to close and extend below the lower edge of the mouth when the deflector is closed.

(No model.)

This flange or top is to prevent water from be ing driven between the deflector and the said lower edge when the deflector isclosed. The gutters intercept and convey out of the ventilator any water that may pass laterally off the upper surface of the deflector. The deflector 0 may be made without the lips fand d; but it is preferable to have them, as they serve as additional means of preventing water from working into the ventilator.

There is attached to theupper de=flector,B,a chain, cord, or rope, g, which, after being led partially around two guide-wheels, h 'i, arranged in the hood in the manner as represented, is connected to a rod, 7., adapted to slide vertically within the duct lsurmounted by the hood. A small pan or vessel,m,is attached to the rod is at its lower end, Such pan being arranged directly over or within a tunnel, it, having its discharge-pipe o furnished with a damper or closing-valve, p, and arranged to carry off any water that-may fall into the tunnel. The up per deflector is to be of sufficient weight, oris to be weighted for it in falling to raise the pan. Should a sea strike the ventilator, and water thereby be caused to flow upward into the hood and over the top of the partition I), such water will drop into the. pan, and by its weight will cause the pan to descend and lift up and suddenly close the upper deflector in order to stop the inflow of water. On the pan thus dcscending a valve, 7, to an opening, 8, in the bottom of the pan will be opened by a projection, t, from such valve being carried against the tunnel, in which case the water in the pan will be discharged from it until theupper deflector may drop down and lift the pan.

While the weather is fair or pleasant the lower deflector is to be kept raised up to the top of the mouth a, in which case air or wind blown against the lower surface of the deflect or will be deflected thereby downward into the hood, and thence down its duct 1; but during bad or stormy weather the lower deflector is to be closed, in which case air on be ing blown against the inclined upper surface of the said deflector will be deflected thereby upward into the hood and over the partition b, and by the curved top of the hood will be turned down into and through the hood, a stay or plate, 1), arranged in the hood in manner as shown, serving to support one of the too pulling on the rod to raise the upper deflector partially or entirely upward, as occasion may require, such deflector being not only to prevent water from being blown or driven upward into the hood, but to regulate the inflow of'a'ir.

My invention differs ver y materially from the car-ventilator shown and described in'th'e United States Patent No. 13,779 to Corbett,-

which is a horizontal duct provided with two flaring mouths, and with two valves and an'intermediate vertical duct.- In my ventilator the duct is vertical and has but one month, a vertical partition arranged in rear of it, and to extend above it within the case, audit also has its deflector O hinged to the partition so as to be movable up to the top or down to the bottom of the month.

\Vhat I claim asmy invention in the-aforedescribed ventilator is as follows, viz:

1. The ventilator-hood provided with the single mouth a, and with partition'b, deflector O, adapted and arranged and to operate there with, substantially as set forth.

2. The ventilator-hood provided with the single mouth a, and with partition I), and the two deflectors B and C, adapted and arranged and tooperate therewith, substantially as set forth.

3. The hood provided with the inclined gutters e, and with the deflector O, and partition 1), arranged with the mouth a of the said hood, substantially as set forth.

4. The deflector 0, provided with the rear lipor flange, c, in combination, and arranged as described, with the hood and its mouth and partition I), disposed as shown.

5. The deflector C, provided with the side lips, (I, in combination, and arranged as described, with the hood and its mouth a, partition I), and gutters e, disposed as represented.

6. The deflector 0, provided with the front lip, f, in combination, and arranged as described, with the hood and its month (t and partition 11, disposed as represented.

7. The combination of the water-intercept ing pan 722, provided with thedischarge-valve, as described, with the tunnel n, and with a ventilator-hood provided with a mouth, a, partition b, and the two deflectors B and 0, all being adapted and arranged to operate in manner and for the purposes substantially as set forth.
